Optimizing Visual Cortex Parameterization with Error-Tolerant Teichmuller Map in Retinotopic Mapping [article]

Yanshuai Tu, Duyan Ta, Zhong-Lin Lu, Yalin Wang
2020 arXiv   pre-print
One key element of the approach is the Error-Tolerant Teichmuller Map, which uniforms the angle distortion and maximizes the alignments to self-contradicting landmarks.  ...  The mapping between the visual input on the retina to the cortical surface, i.e., retinotopic mapping, is an important topic in vision science and neuroscience.  ...  The Error Tolerant Teichmüller Map (ETTM) is proposed to enhance the T-map to tackle landmarks with errors.  ...

Representation is representation of similarities

Shimon Edelman
1998 Behavioral and Brain Sciences  
Advanced perceptual systems are faced with the problem of securing a principled (ideally, veridical) relationship between the world and its internal representation.  ...  I propose a unified approach to visual representation, addressing the need for superordinate and basic-level categorization and for the identification of specific instances of familiar categories.  ...  The Teichmuller space can be parameterized by a small set of real numbers that provide a possible coordinate system for the resulting shape space (Sundararaman 1980) . APPENDIX B.  ...
